CARL AUGUST PAILLARD, OF GENEVA, SWITZERLAND.

ALLOY.

SPECIFICATION forming part of Letters Patent No. 367,161, dated July 26, 1887,

Original application filed March 6, 1886, Serial No.194,525. Divided and this application filed February 24, 1887. Serial No.

228,666. May 11, 1886, No. 38,445.

(No specimens.) Patented in England May 11,1886,No. 6,367; in France May 11, 1886, No. 176,058, and in Germany To all whmn it may concern.-

Be it known that I, CARL AUGUST PAILLARD, a citizen of Switzerland, residing at Geneva, in the canton of Geneva, Switzerland, have invented certain new and useful Improvements in Alloys; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to a metallic alloy, and is composed of the metals hereinafter mentioned, or their equivalents, and is useful in the mechanic arts, and particularly in the mechanisms of watches, chronometers, and

clocks, more fully hereinafter set forth and described. V

The object of my invention is to produce an alloy which will be unoxidizable and non-magnetic.

A further object of my invention is 'to produce an alloy which may be raised by tern: pering to a very high degree of hardness.

In an application filed by me on March (3, 1886, Serial'No. 194,525, of which this is a division, I have fully set forth the importance and utility of an alloy which possesses the characteristics and properties of being nonmagnetic and unoxidizable in the manufacture of balances, spirals, and other mechanisms used in watches, chronometers, and other timepieces, and the means and method of producing such alloy.

In order that the best results maybe obtained in watches and chronometers, I have found that it is necessary that other parts of the mechanism employed therein--viz,, the escape-wheel,escape-lever, guardpin, and reg ulator-index-shall possess the same charac' teristics and properties, and in addition thereto be capable of being tempered to a high degree .of hardness to prevent wear and abrasion.

All of the characteristics above named are possessed by the alloy hereinafter described, which may be tempered to a degree of hardness equal to hard steel. r

This alloy is composed of the following metals, in about the proportions named,-viz: palladium, forty-five to fifty parts; silver, twenty to twenty-five parts; copper, fifteen to twentyfive parts; gold, two to five parts; platinum, two to five parts; nickel, two to five parts; steel, two to five parts.

A process by which this alloy may be formed is fully described in the application of which this application is a division, and hence it is not here again repeated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. Analloy composed of palladium, silver, copper, gold, platinum, nickel, and steel, in about theproportions stated.

2. Analloy composed of palladium, fortyfiveto fifty parts; silver, twenty to twenty-five parts 5 copper, fifteen to twenty-fi ve parts; gold, two to five parts platinum, two to five parts; nickel, two to five parts; steel, two to five parts, substantially as described. 7 p

In testimony whereofI affix my signature in presence of two witnesses.
